Bacteria Could Help Build Sustainable, Eco-Friendly Construction Materials

Scientists at the University of Bath are examining whether the natural properties of bacteria might help in establishing a brand-new type of environmentally friendly plasterboard.
They are working with start-up business Adaptavate, which makes sustainable building products. Their naturally degradable plasterboard, Breathaboard utilizes compostable crop waste rather of gypsum, is lighter, and has much better acoustic and thermal insulation compared with conventional plasterboard.
Microbiologists from the University of Baths Department of Biology & & Biochemistry, and concrete experts from the Department of Architecture and Civil Engineering have actually been awarded financing by the National Biofilms Innovation Centre (NBIC), for a six-month pilot job that aims to enhance the homes of the prototype plasterboard using their bacteria-based building technology (BBCT).

If successful, the plasterboard can be scaled up and developed further.
Dr. Susanne Gebhard, Senior Lecturer in the Universitys Department of Biology and Biochemistry and the Milner Centre for Evolution, is leading the project in partnership with Professor Kevin Paine from the Universitys Department of Architecture and Civil Engineering.
She said: “Biofilms are formed when germs stick to coat a surface area, instead of growing neat dot-shaped clumps on a petri dish.
” This is an actually amazing project that will see whether we can exploit the natural biofilm-forming abilities of germs to function as a sort of glue that will help improve the residential or commercial properties of biodegradable building products.”
Jeff Ive, Technical Director at Adaptavate, stated: “Gypsum is the third most utilized construction material and represent 3% of UK carbon emissions.
” Its either mined or produced from waste from coal power stations and is ending up being significantly expensive to produce. As its calcium sulphate based, it likewise requires to be dealt with thoroughly so it doesnt damage the environment.
” Our Breathaboard is a low carbon sustainable option to gypsum based plasterboard and might make a genuine distinction to the carbon emissions of the building industry.
” Were pleased to be working with the University of Bath to more develop this item.”
